Definitions

  • the invention relates to an apparatus for detecting and correcting anomalies in the equilibrium of the human body, based on the interpretation of the distribution of the weight of the body on the bearing points of the feet.
  • the center of gravity of the human body is situated at the level of the third lumbar vertebra which forms one of the most important points of the spinal column for maintaining equilibrium, at the same time as one of the most vulnerable for it supports all the weight above it whereas all the party of the body below it is suspended therefrom.
  • This third lumbar vertebra is the seat of the most current lesions of the column, for in all the changes of posture due to the mobility and to the locomotion of the human body, the center of gravity tends to maintain a vertical line going from the top of the head to the center of the planter arch, that is to say that all the movements of the body pass through this vertebra.
  • the slightest bone or muscular lesion results in an attempt to compensate in the sense of a normal vertical line between the feet and the head which will result in an imbalance and a poor distribution of the loads on the plantar arch.
  • the plantar arch does not form an equilateral triangle but has three arches and three bearing points which form a comparable structure.
  • the bearing points are included in the contact zone with the ground which receives the plantar impression and they correspond to the head of the first metatarsal, to the head of the fifth metatarsal and to the posterior tuberosities of the calcaneum.
  • Each bearing point is common to two adjacent arches.
  • the internal arch (calcaneum-head of the first metatarsal) has the scaphoid as ground
  • the external arch (calcaneum-head of the fifth metatarsal) has the large apophysis of the calcaneum as crown.
  • the front arch (head of the first metatarsal, head of the fifth metatarsal) has as crown the head of the second metatarsal.
  • the weight of the body is distributed half on the forefoot and half on the rear foot, in line with the extension of the front edge of the leg, which corresponds to the crowns of the internal and external arches, that is to say to the center of the instep.
  • the distribution of the bearing pressures on the ground is very important for attaining equilibrium. In fact, it is the bearing pressures perceived by the sole of the feet which inform the nervous system as a whole, including internal ear and cerebellum. By reflex movements all the muscles for maintaining verticality, for opposing gravity contract and equilibrium is attained.
  • Apparatus which allow the user to visualise the distribution of his weight on each of his legs and which include essentially two mobile bearing surfaces, independent and having a connection device of the same kind as the linkages existing in weight scales, which translate on a scale the difference of weight applied to each of these surfaces.
  • connection device of the same kind as the linkages existing in weight scales, which translate on a scale the difference of weight applied to each of these surfaces.
  • subsidiary devices are added, such as cross ruled mirrors by means of which the person may have the image of his body and himself rectify the disymmetry of his position.
  • a construction such as described in FR-A-2 443 235 is also known in which two stages of superimposed plates rest on the ground with interpositioning of dampers between each stage, the upper stage being formed of two independent plates on which the feet come to bear, each plate being associated with an inclination indicator.
  • the invention brings a solution to this problem in that it provides an apparatus which allows not only poor distribution of the weight of a person on his two feet to be detected, but also an imbalance of distribution of the weight on the plantar arch, which apparatus is further extremely accurate, very simple to manufacture and use, which makes it particularly well adapted for arousing in numerous persons efficient correction reactions.
  • the apparatus of the invention includes a single mobile plate which rests, through at least three deformable members, on a base bearing on the ground and which includes an indicating member of the spirit level kind, integral with the movements of this latter, said mobile plate, further having elements marking the positioning of one or of both feet formed of axial lines along the axis of the feet, as well as a removable system for fixing the foot with respect to a transverse line dividing the weight of the body, in the middle of said plate.
  • the removable fixing system is formed of a rigid half frame cooperating with notches provided on the plate at the ends of the transverse median line or of a resilient strip retained by said notches or else a comb cooperating with holes provided on the axial lines and the transverse lines.
  • FIG. 1 a perspective view of the apparatus
  • FIG. 2 a top view of the support plate showing bearing of the two feet
  • FIG. 3 a perspective view of a variant of construction of the upper plate
  • FIG. 4 a top view of a variant of construction of the support plate
  • FIGS. 5 and 8 perspective views of a variant of construction of the apparatus
  • FIGS. 6 and 7 two schematical perspective views showing variants of fitting the spirit level.
  • the apparatus shown in FIG. 1 includes essentially a base 1 bearing on the ground through four supports adjustable in height by means of a wheel 3.
  • the base is provided at its four corners, in line with the feet, with four recesses 4 serving as housing for springs 5.
  • These springs made advantageously from steel, are of equal height, of equal calibration and sufficiently resistant to crushing to prevent the plate from abutting against base 1 when it supports its load.
  • An upper plate 6 of a size similar to that of the base rests by its four corners on springs 5. It is also provided with recesses 7 in which said springs are positioned. At the upper part of the plate is set a spherical spirit level 8 possibly covered with a magnifying lens.
  • Plate 6 is made from a rigid and undeformable material such as a plywood, a plastic material or a fairly thick metal sheet.
  • the apparatus includes on its upper plate a transverse line AA' and an axial line BB' in accordance with the axis of the feet at the end of which is situated a spirit level 8, the two lines being the medians of the square formed by plate 6.
  • Other lines CC' and DD' parallel to the lines BB' are disposed symmetrically on each side of this latter, with even spacing, the outer lines DD' being substantially at equal distances from the edge of the plate and from the axial line BB'.
  • the user may thus place the internal edges of each foot along lines CC' or DD' so that the bearing force of his right foot and of his left foot are distributed symmetrically with respect to the axial line BB' as can be seen more precisely in FIG. 2.
  • frame 18 may be replaced by a resilient material, of a form similar to that of a strip, this strip would pass around the apparatus above and below, and would be retained in notches 17 so as to be perfectly superimposed on the transverse line AA'. The user would slide his feet under the resilient strip until the front edge of the leg is reached.
  • the feet are placed along lines CC' or DD', as mentioned above, and they are engaged under the frame until the front edge of the leg comes into abutment against the horizontal part of the frame.
  • the center of the instep corresponding to the crowns of the internal and external arches of the bearing points of the body, is then centered on the points at which the transverse line AA' meets the axial lines CC' and DD' underlined by crosses + shown in FIG. 2. It is recommended by means of a pencil to mark the impression of each foot on the upper plate 6 so as to avoid fixing at each exercise. It is obvious that the fixing systems will be removed after the feet are correctly positioned on the apparatus.
  • lines CC' and DD', parallel and equidistant from the large median line BB' may be pierced with small holes 19, in which will be placed the six teeth of a comb 20, the comb projecting from the surface of the plate and serving as a guide or setting for the internal edge of each foot.
  • the same system of holes in the transverse line allowing the use of the comb is possible.
  • the holes may in all cases pass through the whole of the upper plate 6 through its thickness. If the apparatus is used while wearing shoes, the comb will be cleared by pulling it upwards until it comes into contact with the lower part of the front edge of the leg. In all cases, the fixing systems will be removed after the feet have been positioned and before use of the apparatus.
  • the apparatus is used for diagnosing and correcting upright imbalance, without moving, but also stopped movement equilibrium, such for example as equilibrium in a squatting position.
  • the foot must remain strictly bearing on the upper plate through its three bearing points, and not moved despite the changes of shape of the arches which tend to be crushed normally, the leg on the other hand changes orientation and any transverse fixing system left in position would be a hindrance to the squatting position.
  • the invention is based on a perfect positioning of the feet on the apparatus. In fact, it is known that the vertical equilibrium of man on two feet or on one foot, corresponds to the fair distribution of his weight over the three bearing points of the plantar arch.
  • FIG. 4 illustrates a variant of construction in which the plate is square, but the spirit level is located in a corner and the lines CC' and DD' are oriented as shown on each side of the axial line BB'.
  • the outer form of plate 6 may also be circular as shown with a broken line.
  • base A bears on the ground through fixed feet 9.
  • spirit level 8 is then mounted on an adjustment ball joint 10 which allows the bubble to be centered and consequently allows the uneveness of the ground to be counterbalanced before using the apparatus.
  • This ball joint mounting would also allow an upper plate to be used which is slanted with respect to the ground.
  • spirit level 8 is fixed to a column 11 or to a rod 12 mounted on tripod and adjustable in height, both being fixed to plate 6.
  • Each also has an adjustment ball joint 10. This arrangement brings the spirit level closer to the eye of the user.
  • a counterweight 13 is moreover fixed to the plate for compensating for the weight of the column or the rod.
  • plate 6 is provided with a central recess 14 which serves as housing for a personal weighing machine 15 with its weight indicator 16.
  • the weighing machine is centered so that the user may place his feet thereon in alignment of the axial line CC', DD' and AA'.
  • the center of gravity of the body is in its right position and the bubble of spirit level 8 is perfectly centered. Any offsets of this bubble from the center corresponds to an imbalance of the body and to a poor distribution of the weight at the level of the foot.
  • the user sees it visually and may himself, by muscular action, provide the correction of his anomaly of equilibrium by accentuating the pressure of one foot or of both towards the front or towards the rear so as to progressively bring the bubble back to its central point.
  • the position of the bubble before correction informs the user about the orientation or the compensation which he must carry out.
  • the apparatus thus allows the user to ensure the correction immediately after this diagnosis of the imbalance, for he has been conscious of the plantar perception which is an essential factor in maintaining equilibrium, which caused him an osteoarticular and muscular reaction.
  • the repetition of these movements for centering the bubble lead the user progressively to eliminate the insufficiencies of some muscles by causing them to work so as to arrive at equilibrium of the body.
  • the transfers of weight at the level of the feet may be studied on floors of different slants and diagnosises may be made as to the bearing defects at the level of each bearing point of the plantar arch.
  • the possibility which the invention offers is important in the practice of different sports where the transfers of bearing force are necessary and require fine coordination: for example skis, surfboards, surfing, golfing . . . etc.
  • the exercises whether they are on a flat ground, with the bubble of the spirit level centered on the plate parallel to the ground, or with the bubble of the spirit level centered on a slanted ground, by raising one or both feet from the apparatus, always put the center of gravity of the body in its place.
  • the exercises may be crouching exercises where all the body comes into play in the search for equilibrium. But they may also be exercises which leave the upper part of the body fixed from the center of gravity and mobilize the lower part of the body or conversely. After use the user feels a correct comfortable bearing force which is called balance on the ground. He holds himself better vertically, walks better and keeps his stabilizing musculature correctly in all his movements from information acquired during use of the apparatus. Daily upkeep and the execution of different exercises of short duration on the apparatus is sufficient for correcting the right posture, for correcting current deformations, for giving correct tonicity back to all the equilibrium muscles, so for giving the body again equilibrium and flexibility coordination.
  • this invention allows the imbalances to be studied under numerous conditions and bearing force imperfections to be detected at the same time as the unsatisfactory muscular responses and allows them to be corrected.
  • all the muscular chains of the posture may be studied.
  • the nervous system being the link between the bearing force on the ground and the muscular response of equilibrium, it will be readily understood that this apparatus will find numerous applications in neurology.
  • the spirit level used could be a pendulum whose movements will be detected and transmitted electrically, for example through resistors or electric contactors associated with light indicators.
